-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : kernel 2.4 SUMMARY : Local denial of service vulnerability DATE : 2002-12-16 17:41:00 ID : CLA-2002:553 RELEVANT RELEASES : 7.0, 8 - ------------------------------------------------------------------------- DESCRIPTION The Linux kernel is responsible for handling the basic functions of the Conectiva Linux operating system. Christophe Devine reported[1] a vulnerability in versions prior to 2.4.20 of the linux kernel that could be exploited by a local non-root user to completely "freeze" the machine. A local attacker could exploit this vulnerability to cause a Denial of Service (DoS) condition. This update fixes this problem. Please note that the updated kernel packages here listed are available in our update servers since November 20, 2002. SOLUTION All users should upgrade the kernel immediately. IMPORTANT: it is not possible to use apt to apply kernel updates. These packages have to be updated manually. Generic kernel update instructions can be found in our updates page[2]. Kernel 2.2 users in Conectiva Linux 6.0 and 7.0 are also vulnerable to this issue. It is recommended that these users upgrade to the latest (2.4) kernel, but updated packages for the 2.2 series are being prepared and will be released in a near future.
